Active dynamic thermal storage for industrial processes

Active thermal storage implies storing heat or cold for reuse as needed. For energy-efficient industrial heating and cooling this research application addresses how to integrate multiple energy sources, and to store heat and cold for rapid dynamic usage. In order to do so the proposal seeks to investigate opportunities within dynamic thermal energy storage (DTES) integrated into practical operational systems. What are the scope and main para¬meters for turning this source of renewable energy into broad re ality in a future facing global heating, dwindling oil resources and historically increasing demand for energy? Our research hypothesis is that one may utilise natural variation in ambient temperature and radiation as a genuine source of renewable energy . This requires integration of multiple sources of energy to obtain increasingly efficient heating and cooling in industrial processes and also for indoor comfort in buildings. Dynamic Thermal Energy Storage (DTES) may play a significant role in this inte gration. Our primary objectives are to study how the concept (i.e. dynamic thermal storage) may enhance industrial heating and cooling processes by: 1. Further study of the DTES concept for industrial heating and cooling 2. Further study of the interacti on and synergy between DTES and other technologies such as BTES (Borehole Thermal Storage) and heat pumps in serving industrial efficient heating and cooling. 3. Modelling, optimisation and testing of the DTES concept for generic application. 4. Computeri sed control and optimisation of integrated system, that also includes weather forecasts. 5. As a case a modern greenhouse facility is chosen, integrated with heat pumps and heat exchangers, based on computerised modelling and a practical installation at t he Mære Landbruksskole in Nord-Trøndelag, Norway.
